Having problems installing PSQL v11 on 64bit windows 7 pro. Help

So i have clean installed windows 7 pro, and ultimate 3 time since yesterday . i had ultimate first but thought maybe that might be causing problem . So went ahead and re installed Windows 7 pro 64 bit.Did all the updates and after installing pervasive igo in start menu and folder . When i click on any app from pervasive it says configuring pervasive ( its Microsoft window) and acts like trying to install something and then it quits. what could be causing it and how can i fix it?
